If countries report data under water quantity and emissions to water in 2013, this will be used to pre-fill the 2014 Eurostat/OECD Joint Questionnaire and no Eurostat reporting has to be done by the country. In addition, the questionnaire will be pre-filled with some parameters introduced under UWWT Directive - Article 15 - implementation for 2013 reporting.
